Xerath (Q) cancels itself Bug

This bug is fixed now. It was caused by a change that fixes a long-standing bug where champions affected by overlapping crowd control effects could occasionally use abilities. After we realized that the change for overlap cc broke a few champion abilities (including Xerath's Q when you use quick cast), we turned it off.

We will be modifying the abilities that broke, so that they work properly with the overlap cc change, on and re-enable the change for overlap cc in a future patch.
